A surgical instrument, in at least one form, includes an end effector and a power module. The power module may include a first motion conversion assembly. The first motion conversion assembly includes a first rotary drive and a first axial drive operably coupled to the first rotary drive. The power module may further include a second motion conversion assembly which may include a second rotary drive and a second axial drive operably coupled to the second rotary drive. The power module may further include a motor configured to generate at least one rotational motion to actuate the end effector and a transmission assembly configured to selectively engage the motor with the first rotary drive and the second rotary drive, wherein the motor is concentrically arranged with the first rotary drive and the second rotary drive.
1. A surgical instrument including an end effector and a power module, the power module comprising: a first motion conversion assembly, comprising: a first rotary drive; anda first axial drive operably coupled to the first rotary drive;a second motion conversion assembly, comprising; a second rotary
1. A surgical instrument including an end effector and a power module, the power module comprising: a first motion conversion assembly, comprising: a first rotary drive; anda first axial drive operably coupled to the first rotary drive;a second motion conversion assembly, comprising; a second rotary drive; anda second axial drive operably coupled to the second rotary drive;a motor configured to generate at least one rotational motion to actuate the end effector, the motor defining an actuation axis; anda transmission assembly configured to selectively operably couple the motor to the first rotary drive and the second rotary drive, wherein the first rotary drive is rotatable about the actuation axis in response to the at least one rotational motion when the motor is operably coupled to the first rotary drive, and wherein the second rotary drive is rotatable about the actuation axis in response to the at least one rotational motion when the motor is operably coupled to the second rotary drive. 2. The surgical instrument of claim 1, wherein the first axial drive is movable a first axial distance relative to the first rotary drive, wherein the second axial drive is movable a second axial distance relative to the second rotary drive, and wherein the first axial distance is different from the second axial distance. 3. The surgical instrument of claim 1, wherein the motor is positioned at least partially within the second rotary drive. 4. The surgical instrument of claim 1, wherein the second rotary drive is positioned at least partially within the first rotary drive. 5. The surgical instrument of claim 1, wherein the first axial drive and the second axial drive partially extend between the first rotary drive and the second rotary drive. 6. The surgical instrument of claim 1, wherein the transmission assembly includes a transmission member movable to a first position wherein the motor is operably coupled to the first rotary drive and a second position wherein the motor is operably coupled to the second rotary drive. 7. A surgical instrument, comprising: a shaft;a housing extending proximally from the shaft;an end effector extending distally from the shaft; anda power module at least partially positioned within the housing, the power module comprising: a first rotary drive;a second rotary drive;a motor configured to generate at least one rotational motion, the motor defining an actuation axis; anda transmission assembly configured to selectively operably couple the motor to the first rotary drive and the second rotary drive, wherein the first rotary drive is rotatable about the actuation axis in response to the at least one rotational motion when the motor is operably coupled to the first rotary drive, wherein the second rotary drive is rotatable about the actuation axis in response to the at least one rotational motion when the motor is operably coupled to the second rotary drive, and wherein the motor extends along the actuation axis. 8. The surgical instrument of claim 7, wherein a first axial drive is movable a first distance relative to the first rotary drive, wherein a second axial drive is movable a second distance relative to the second rotary drive, and wherein the first distance is different from the second distance. 9. The surgical instrument of claim 7, wherein the motor is positioned at least partially within the second rotary drive. 10. The surgical instrument of claim 7, wherein the second rotary drive is positioned at least partially within the first rotary drive. 11. The surgical instrument of claim 7, wherein the first rotary drive is threadedly engaged with a first axial drive, and wherein the second rotary drive is threadedly engaged with a second axial drive. 12. The surgical instrument of claim 7, wherein the transmission assembly includes a transmission member movable to a first position wherein the motor is operably coupled to the first rotary drive and a second position wherein the motor is operably coupled to the second rotary drive. 13. The surgical instrument of claim 12, wherein the transmission member is movable to a neutral position, wherein the motor is operably disconnected from the first rotary drive and the second rotary drive in the neutral position. 14. The surgical instrument of claim 13, wherein the neutral position is located along the actuation axis between the first position and the second position. 15. The surgical instrument of claim 7, wherein a first axial drive and a second axial drive partially extend between the first rotary drive and the second rotary drive. 16. The surgical instrument of claim 7, wherein the transmission assembly includes a transmission shaft separably couplable to the motor, and wherein the transmission shaft is movable to operably disconnect the motor from the transmission assembly.
